Hell hath no fury...or, in this case, Heaven, as it's a celestial maiden or "ten'nyo" who's unleashing it! The search for Ceres' hagoromo or "celestial robes" brings the action back to Tokyo--to Miyagi, specifically, where rumors of a spectral white dog ("figuring in the celestial legend!," says Suzumi) prompt a transfer to girls-only high school for Aya, Chidori, and...Yûhi?! Connected to the dog's increasingly frequent attacks is a sweet and popular girl named Maya Hirobe, but why--and more importantly, how--is she involved? Is it possible that Maya is a C-Genome...and doesn't even know it?
